Flint and Walling Water Well Submersible Pumps, Centrifugal and Self Priming Sprinkler Pumps, Jet Pumps and Water System Accessories are all available from Dean Bennett Supply where we welcome the Do-it-yourself installer. Call 1-800-621-4291 to select your well supplies.

Flint and Walling 5 gpm 1/2 hp submersible pump is ideal for a well between 60' and 225' deep. Since you pump water from the static water level, which is the distance from the well top down to the water, at 30-50 pressure switch setting the 1/2 hp 5 gpm submersible pump will produce between 7.9 gpm at 40 psi at 60' of total lift, and will still deliver 4.2 gpm at 225' of depth at 40 psi, if the water level ever draws down to there.

When sizing your pump wire, you need to take the distance from the power panel where the meter supplies the power, out to the well, and down to the submersible pump in the well. With the 1/2 hp submersible pump set at 225' depth and a run to the main power panel of 150' you size your pump cable wire for 375' total run to the 1/2 hp motor. With the 1/2 hp 230V single phase motor running 375' total, we would need to run #12 wire to the pump. The #12 pump wire can run up to 650' total with the 1/2 hp pump motor.

When sizing a water pressure tank for use with the 1/2 hp 5 gpm pump, you should select a bladder type pressure tank that has a minimum draw down of 7.9 gallons. This way you prevent short cycling the pump, because when it turns off, the pump can rest for 1 full minute before turning back on. If we use a 30-50 pressure switch on the tank fitting kit, we would need to select a minimum size water pressure tank of AT122 which gives you 10.3 gallons of draw down, usable water from the tank before the pump turns back on. A larger pressure tank is OK if you desire, as it will increase the usable water between pump cycles.

5 GPM 1/2 hp 4" Complete Submersible Pumps
( Includes pump end, motor and control box )
1/2 hp pumps are available in 115V or 230V single phase and are available
either 3 wire with control box or 2 wire without need for a control box.
Most installations use the 3 wire with control box model, since it provides a
point of protection for the motor on the surface of the well. If you get a
lightning strike, many times you can just change the control box.
If you use the 2 wire motor, the controls are built into the bottom of the pump motot,
requiring you to pull the submersible pump up from the well to service it.
